A randomized controlled trial comparing myoinositol with metformin versus metformin monotherapy in polycystic ovary syndrome

Abstract

Objective: Insulin resistance and hyperinsulinemia plays an important role in pathogenesis of polycystic ovary syndrome (PCOS). Metformin, Myoinositol and d-chiro-inositol acts as insulin sensitizers and exerts a beneficial effects in PCOS. The objective is to compare the effect of metformin monotherapy versus a combination of metformin with Myoinositol and d-chiro-inositol in PCOS. Design: This study is a randomized controlled trial conducted over a period of 6 months. All overweight and obese women with PCOS with the age group between 18 and 35 were included and randomized into two groups, 27 in the metformin monotherapy arm and 26 in the myoinositol combination arm. Patients and Measurements: The variables assessed were duration of menstrual cycle, anthropometric parameters, modified Ferriman Gallwey score, global acne score, Fasting insulin, HOMA-IR, fasting lipid profile, serum testosterone, sex hormone binding globulin, luteinizing hormone, follicle stimulating hormone, anti-Mullerian hormone, and pelvic ultrasound to assess ovarian volume, PCOS Questionnaire score. Changes in the parameters from baseline at the end of 6 months of treatment were assessed and compared between the groups. Results: Menstrual cycle regularity improved in both groups with significantly greater improvement in the group receiving myoinositol-based therapy (p
